PROCESS OF FORMING HYGIENIC METALLIC ENDS 0N CIGARS AND THE LIKE.

I Specification of Letters Patent.

Patented March 24, 1908.

Application filed August 19, 1907. Serial No. 889,098.

To all whom it may concern;-

Be it known that I, ANNE AUKE VAN DER MEULEN, manufacturer, a subject of the Dutch'Queen, and residing at Amsterdam, 4 Vondel Kerkstraat, Netherlands, have invented a new and useful Im roved'Process of Forming Hygienic Metallic nds on Cigars and the Like; and I do hereby declare the following to be a full, clear, and exact descri tion of the same.

y present invention has for its object to provide a process of forming at the ta .ering end of cigars a metallic deposit, whic will perfectly adhere to and form one with the cover sheet of the cigars and cannot be detach'ed therefrom. without removing the cover sheet itself. This metallic coating serves the purpose of avoiding direct contact between the tobacco and the li s of-the smoker, and therefore complies wit a very im ortant hygienic requirement.

n order to carry the process into practical effect, the ends of the cigars are singly dipped into a suitably composed liquid, prepared as follows: 75 grams of purified para rubber or other rubber are dissolved in about 3 liters benzin. 175 grams of this solution are then placed into a suitable recipient, preferably made of stone, earthenware or the like, and 50 grams of talc powde-r, 40 grams ofbenzin and 20 grams of aluminium powder are added to said solution: After thoroughly stirring, the mass is ready for use. A bunch of cigars is dipped with the tapering ends into said liquid mass, held therein during a relatively short time (say 15 seconds), and then withdrawn vertically, to permit the excess of liquid of falling from the cigars. The latter are then placed with the coated ends u on a support of stone or metal, wherein t e last drops flow off very easily. The bunch of cigars is nowplaced with the tapering and coated ends turned upwards and dried in this position during half an hour. Before di ping cigars into the above described liqui the latter must be' well agitated, The cigars may be dipped into the same either in adry or still moistened state. Instead of preparing the said bath or liquid by means of aluminium, I may use gold or gold-like, and

silver or silver-like metals mixed together in an proportions to obtain the desired effect.

W en-the cigars are to be acked into boxes, when still in a moistene state, they are preferably placed with their tapering metallic ends alternating with their opposite ends. I

The metallic coating obtained by my im- There are two particularly characteristic features of my invention, first, that para rubber is exclusively employed as the binding or adhesive medium, and second that an absolutely opaque insoluble metallic powder is made use of as the solid base of the compound. It is by virtue of these two features that'the advantages of the present invention are attained- The para is ori inally made soluble b a solvent which abso utely evaporates. his is unlike previous processes, in which, Wherever rubber was used, it has been in a solution of substances which did not wholly evaporate,- but themselves formed a coating or deposit of certain thickness. It

is on account of this fact, that exclusively para rubber in a solution which entirely evaporates is used, that the deposited coating is of microscopic thinness on the tobacco. But with-such a coating of microscopic thinness, it is evident thatan absolutely protecting opaque non-porous base must be'used, V

and for this purpose, I have found metallic aluminium powder to be very effective Though I have described my invention as being for a composition containing aluminium and the like, it is manifest that I am free to use any desired metal or any other suitable material as a substitute for aluminium. On the other hand, for the above described dissolving and adhering materials may be substituted any other equivalent substances without departing from the scope of the invention.

Having fully described my invention, what i I claim and desireto secure by Letters Patent is benzin, adding talc powder, benzin and In testimony whereof, I have signed my aluminium powder in proportion of 50, 40 I- name to this specification in the presence of 10 and 20lgra1ns respectively, stirring?i the mix(; two subscribing witnesses.
